CORRUGATED STEEL END FOR RAILWAY CARS.

Application filed May 19,

My invention relates to a sheet metal end structure for railway cars, particularly box cars provided with ribs or corrugations to give the structure strength and rigidity sufiicient to withstand the thrusts and pressure of shifting cargoes and to check the tendency of the superstructure of the car to weave. The stresses against the end because of the shifting of the lading are likely to be more violent near the floor of the car than against the upper port-ion of the end wall since the heavier articles, and those which shift most easily, are likely to be placed on or near the floor.

Having in view a construction which will be as light as possible consistent with strength and rigidity and which can be manufactured at a relatively low cost, my invention has for its principal object to provide a corrugated steel end structure for a railway box car so formed as to be strongest and most rigid in the region nearest the floor of the car, for example, for about one-third the distance from the floor to the roof.

The invention consists in the novel and improved constructions, arrangements and devices to be hereinafter described and shown for carrying out the above stated objects and such other incidental objects as will appear from the following description of certain preferredembodiments of the invention shown in the drawings.

In the drawings Fig. 1 is an end elevation of the superstructure of a railway box car showing the end wall constructed in accordance with my invention.

Fig. 2 is a sectional view on line 22 of Fig. 1.

Fig. 3 is a sectional plan on line 33 of Fig. 1. I

Fig. 4 is a view similar to Fig. 1 showing a modification, and

Figs. 5 and 6, sectional views 011 lines 55 and 66, respectively, of Fig. 4.

Like characters of reference designate like parts in the several figures of the drawings.

Referring first to Figs. 1, 2 and 3, 10 des- 1919. Serial No. 297,998.

ignates the end sill of the car which is shown as consisting of an angle bar, 11 the side sills, 12 the flooring, 13 the end plate which is also of metal and angular in cross section, 1et the side plates, 15 the rid e pole, l6-the roof boards, 17 the corner posts, and 18 the side sheathing.

The end structure comprises, in the embodiment of the invent-ion shown in'these figures, a lower metal sheet 19 formed with a plurality of horizontal corrugations 20 which terminate within the edges of the sheet leaving flat margins 21 and. merge one into the other so as to give the structure a sinuous configuration in cross section. The lower edge of the sheet is secured to the end sill 10 by rivets 22. The flat marginal portions of the sheet at the ends of the corrugations are bent over to form flanges 23 which overlap the side sheathing 18' and are secured to the corner posts 17 through the sheathing boards.

The structure comprises also one or more metal sheets arranged above sheet 19. For example, in the arrangement shown, there are two such sheets, an upper flat sheet 24 and an intermediate sheet 25. The upper edge of the upper sheet is overlapped by and secured to the vertical web of the end plate 13. The lower edge of sheet 24 is overlapped and riveted to sheet 25 and the lower edge of sheet 25 is overlapped and riveted to the sheet 19, the sheets 2% and 25 being provided with flanges, similar to sheet 19 for attachment to the side walls of the car. These sheets are preferably made of thinner metal than the lower sheet 19. The intermediate sheet may facilitating the pressing of theintermediate sheet. I

The sheet metal end structure, as described, is preferably provided with a lining consisting of vertical boards 27 fastened at the top i by bolts 28 to the end plate-13, at the bottom by bolts 29 to a cleat 30 fitted into one of the corrugations of the lower sheet and at intermediate points in. a. similar manner to cleats 31 fitted into two of the corrugations of the intermediate sheet 25.

In the construction shown in Figs. 4, 5 and 6, the corrugations, instead of being of substantially uniform width from end to end, are widest at the middle of the car and taper toward the sides, lhe construction as shown, comprises a lower sheet 32 formed with corrugations or embossments 33 which are deepest and widest along the center or vertical line of the end and taper down to nothing toward the sides of the car, an intermediate sheet 34-. formed with corrugations 35 of similar contour but narrower and shallower at their places of maximum cross sectional area, and a Hat upper sheet 36. The lower edge of the lower sheet is shown as fastened between angle bars 37 forming part of a built up end sill 38.
